The MOTU UltraLite AVB is an 18-input, 18-output audio interface with DSP mixing, wi-fi control, AVB audio networking and best-in-class analog audio quality for on-the-go mobile audio recording.

36 simultaneous audio channels - The most I/O ever offered in the UltraLite series

You get 2 mic inputs, 2 guitar inputs, 6 line inputs, 8 line outputs, headphone out and 8-channel optical I/O for a total of 18 inputs and 18 outputs, simultaneously. The optical ports also support stereo TOSLink (optical S/PDIF).

Best-in-class analog audio quality - Performance suitable for the most demanding situations

The UltraLite AVB sets a new standard for analog audio performance in a mobile audio interface. The eight balanced analog outputs deliver a stunning 117 dB dynamic range.

Universal connectivity - Class compliant USB 2.0 plus audio over Ethernet

The UltraLite AVB connects to your computer with audio class compliant hi-speed USB 2.0 (compatible with USB 3.0 and iOS) for across-the-board compatibility now and in the future. Alternately, if you have a Mac running OS X Yosemite (10.10) or later, you can use a standard Ethernet cable for operation as an audio interface.

DSP-powered mixing - Console-style mixing with 48 channels and 12 busses

The mixer in the UltraLite AVB is a departure from earlier models. In fact, it's identical to the mixer found in MOTU's flagship 1248 and 16A interfaces.

Modeled analog EQ and compression - Vintage processing with 32-bit float precision

British analog mixing consoles are renowned for their musical EQ profiles. The UltraLite AVB meticulously models these classic EQs to give you the very same, magical EQ response found on these coveted desks. Each input channel also provides a classic compressor with peak/RMS operation.

Groups and the Main Mix bus are equipped with MOTU's Leveler™, an accurate model of the legendary Teletronix™ LA-2A™ optical leveling amplifier, known for its highly sought-after Automatic Gain Control (AGC) characteristics.

Web app control - Control everything from your laptop, tablet and smartphone

The software that you use to control the UltraLite doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the UltraLite's on-board DSP, mixing, device settings, and network audio routing from the web app software running in your favorite web browser on a laptop, tablet or smartphone connected by wire or Wi-Fi to your local area network. Use any web client on any platform — Mac, Windows, Linux, iOS, Android — as long as it shares the same network.

Stand-alone mixing with wireless control - Control everything from your iPad or iPhone

Connect an Apple Airport™ or other Wi-Fi router directly to the UltraLite with a standard Ethernet cable and control the UltraLite AVB's powerful mixing and DSP effects from your smartphone or tablet, without a computer. Great for live sound mixing.
